      abstract     = {Various transitions that a magnetic Skyrmion can undergo
                      are found in calculations using a method for climbing up the
                      energy surface and converging onto first order saddle
                      points. In addition to collapse and escape through a
                      boundary, the method identifies a transition where the
                      Skyrmion divides and forms two Skyrmions. The activation
                      energy for this duplication process can be similar to that
                      of collapse and escape. A tilting of the external magnetic
                      field for a certain time interval is found to induce the
                      duplication process in a dynamical simulation. Such a
                      process could turn out to be an important avenue for the
                      creation of Skyrmions in future magnetic devices.},
